Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

Changes in the Activity of KCC2 Protein Influence Reward Learning

A new finding from researchers at Georgetown University Medical Center shows that the learning process of associating cues with rewards can be altered by increased or decreased activity of a specific protein in the brain.

Circular Single-Stranded DNA Molecule Can Simultaneously Silence Multiple MicroRNAs

Professor Dongsheng Liu of Tsinghua University, Professor Ziyang Hao of Capital Medical University, and Researcher Yuanchen Dong of the Institute of Chemistry, Chinese Academy of Sciences, have collaborated to develop a circular single-stranded DNA molecule capable of simultaneously silencing multiple miRNAs.

Single-Cell RNA Imaging Uncovers Four Distinct Neuron Bands in the Hippocampus

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have identified a previously unknown pattern of organization in one of the brain's most important areas for learning and memory.

Harnessing Triploid Loquat to Unlock Aneuploid Diversity for Advanced Breeding

Triploid plants are widely valued in horticulture for desirable traits such as seedlessness, yield improvement, and stress resilience.

Ambiguous Stop Codons Expand the Genetic Code in Archaea

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids to make a protein.

Study Uncovers How Polyploid Plants Harness Transposons for Evolutionary Innovation

Polyploidization, the combination and duplication of genomes, is a major driver of plant evolution and diversification. Yet this process causes "genome shock," leading to rapid activation of transposable elements (TEs).

New Regulatory Pathway Enhances Key Aroma Compound in Wine Grapes

β-Damascenone is a key norisoprenoid compound responsible for characteristic floral and fruity aromas in grapes and wines, particularly those from non-aromatic varieties such as Cabernet Sauvignon and Merlot.

Exploring Carotenoid Diversity in Carrots Through Gene Editing

Carrots are rich in carotenoids, essential for human health, providing important compounds like vitamin A.

FOXP3 Gene Regulation Holds Key to Immune Therapies

The immune system faces a delicate balancing act: it must be aggressive enough to fight infections and cancer, yet restrained enough to avoid attacking the body's own tissues.

Animals Evolved Similar Genetic Tools to Conquer Land Across Distant Lineages

Animals from completely different branches of the tree of life such as insects, worms and vertebrates independently evolved similar genetic solutions to survive on land, according to a new study from researchers at the University of Bristol and University of Barcelona.

Rare Stress-Sensitive Neurons Hold the Key to Healthy Brain Blood Flow

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: reduced blood flow.

New Persimmon Genome Assembly Sheds Light on Early Flowering Ability

The genus Diospyros includes over 500 species, among which cultivated persimmon (D. kaki) holds great nutritional and economic importance.

Dual Role of SlNOR and SlNOR-like1 Revealed in Tomato Pollen Development

Successful fertilization in flowering plants depends on healthy pollen development and structural integrity of the pollen wall.

New Genetic Pathway Explains Why Some Citrus Fruits Taste Less Sour

The characteristic sour-sweet balance of citrus fruits is largely defined by citric acid accumulation in the vacuoles of juice sacs.

TRV-Mediated Gene Editing System Transforms Tomato Functional Genomics

CRISPR-Cas9 has revolutionized plant genome editing, yet its application in tomato remains limited due to the plant's recalcitrance to transformation and regeneration.

Warmer Temperatures Drive Faster Immune Responses Through Myosin II Activation

Temperature is a key physiological factor that determines the speed of immune reactions. While this may seem obvious, it has remained largely unexplored at the single-cell level-until now.

Study Unveils the Complete Biosynthetic Loop Regulating Tannin Production in Strawberries

Hydrolyzable tannins (HTs), including gallotannins and ellagitannins, are essential polyphenolic compounds that influence fruit taste, antioxidant capacity, and stress tolerance. Although condensed tannin biosynthesis has been well studied, the enzymatic processes governing HT formation remain unclear.
